With reference to the drawing, 10 desig- .nates' an anvil-member 'o-f the fastener device which as made in my improved 'fo-rm is constructed of sheet stock first in the form illustrated inFigure 2, with its outer wall 11 pierced as" at 12 to form an enlarged 7 opening therethro ughjand the wall about this-opening is turned-inwardly as at 13'to receiveandturn outwardlythe edge '14 of b.

It is also found 'o-f advantage in the manu facture of anvilsfor fasteners of this charaoter, to form the innerinturned wall with a continuous or unbroken surface for several reasons: first, the tools required for turning or rolling this-edge inwardly where the surface is unbroken, are much less eX- pensive to construct than those required forpreparing and rolling a serrated edge inwardly, and second, thetools for rolling an unbroken edge will stand up much longer, do better Work, and from such tools greater production can be obtained. 7 Then again, by the forming of a smooth, continuous and unbroken inner engaging surface on this anvil, it will not cut into the stock of the work which, when formed of a thin kid, is of advantage as when forced onto a smooth surface the stock is not cut or weakened and so injured.

An outercap 22 as illustrated in Figure 5, may be rolled over the anvil member to present an ornamental appearance and the same may be reinforced by plate 23, both the cap and the plate being shown in assembled pos-ition in Figure 1. V

In assembling a fastener of my improved type the edge 14 of the socket member 15 is passed through an opening 19 in the stock 20 and is forced thereinto, the edge l l being The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilegeof resorting to all the mechanical changes to which the device is susceptible, the invention. being defined and limited only by the terms of the appended claim, V
